June Lockhart, who died at the age of 100, started her professional journey in films, but achieved recognition after transitioning almost exclusively to TV. Having been offered limited chances to shine in movies from her first appearance as a child in 1938 until 1947, she thrived on TV in many popular series, especially in Lassie.

Becoming Ruth Martin on Lassie

Taking over from a previous star in 1958, Lockhart remained in the series until 1964. She played Ruth Martin, wed to agriculturalist Paul Martin and the foster mother of seven-year-old Timmy Martin, whose dog was the titular hero of the series.

Even with playing a housewife, Lockhart adeptly avoided being overshadowed by the brilliant animal star. She described the program as “a fairy tale about families on a rural property in which the canine resolves all the problems in 22 minutes, in time for the last advertisement”. After she left the series, Lockhart remarked: “In six sexless years of playing a rural wife and mother, I was rarely allowed to kiss my co-star on the cheek.”

Journey into Lost in Space

Lockhart went directly into a second hit, Lost in Space (1965-68), a semi-spoof sci-fi series targeted primarily at young audiences and based by The Swiss Family Robinson. Lockhart and another actor portrayed Maureen and John Robinson, two scientists investigating alien planets. Lockhart had to spend most of her time deftly trying to navigate visual effects. As the series continued, the storyline became less and less about this interstellar clan and more about the boy and his bond with a mechanical being, and the cowardly villain Dr Zachary Smith.

Initial Career and Family Background

Lockhart’s movie first role, at the young age of 13, had come as Belinda Cratchit in A Christmas Carol (1938). In the parts of her parents, Bob and Mrs Cratchit, were her actual parents, Gene and Kathleen Lockhart. As UK-native Kathleen and Canada-native Gene were both actors in many of movies, as well as on theater, it was almost inevitable that June, who was born in New York, would join the entertainment industry.

Her first stage appearance, at the age of six, came in a non-musical role in an opera at the Metropolitan Opera in New York (1931).

Cinema Career

When her father was offered a deal by a motion picture studio, after his success on Broadway, she relocated with her parents to Hollywood, where Gene made around 300 films. After attending school in Beverly Hills, June started her career in movies, mostly in small roles in acclaimed pictures such as Sergeant York (1941), The White Cliffs of Dover (1942) and Meet Me in St Louis (1944). In the latter, she is delightful as a New Yorker at a household party, whose schedule is filled spitefully to stop Lockhart interacting with her sibling.

More importantly, although she did not realize it at the time, was Son of Lassie (1945). It was one of multiple follow-ups to the hugely successful Lassie Come Home (1943), in which a young star had played the female character who assists the canine to return to the owners. In the subsequent film, Lockhart played the now grown-up character.

The loving way in which she interacted with both Lassie and her offspring, Laddie, protagonist of a wartime story in Nazi-occupied Norway, was in the consideration of the creators when it came to casting the Lassie TV series 13 years later.

Transition to Television and Broadway Achievement

Although she was offered major roles in two thrillers, She-Wolf of London (1946) and Bury Me Dead (1947), Lockhart decided her movie career was getting her nowhere and that TV would be the solution. Before going in a new direction, she received acclaim on Broadway in For Love or Money (1947), a humorous play for which she won a Tony award as best newcomer.

A additional significant run came with Petticoat Junction (1968-70), set in a rural hotel, where Lockhart is a physician and mother figure. She also featured frequently in TV westerns in the 50s, such as Have Gun Will Travel, Wagon Train, Gunsmoke, and Rawhide. Her hectic workload persisted for the next five decades, with a recurring role in General Hospital between 1984 and 1998. Among her many guest appearances were as the actress in a 1988 episode of a talkshow, where the presenter finds a lost collie, and in another sitcom in 1995 as the parent of a restaurant manager.

Later Roles and Achievements

Her last TV credit came in 2021 as the narration of Alpha Control in an episode of a streaming service’s remake of Lost in Space. In the movie version featuring well-known actors (1998), she had a holographic cameo as a school principal. She took joy in learning how much of an inspiration the first series had been to later astronauts, and often attended the agency’s launches and other events. In 2013 her work as a volunteer representative brought her its Exceptional Public Achievement Medal.

Among her limited later feature films was the fantasy, Troll (1986) in which she portrayed a sorceress, with her own daughter, Anne Lockhart, playing her younger self.

Personal Life and Family

In 1951 she wed John Maloney, a physician and former Navy medical officer. In addition to Anne, they had a second daughter, June. That marriage ended in divorce, as did her subsequent marriage, to John Lindsay, an architect.

She is remembered by her daughters and four grandchildren.
